Multi-m far infrared carbon fiber light wave tube

Abstract

This invention provides a multi-M type far-infrared carbon fiber light wave tube, relating to the field of light wave tube technology. It includes a quartz tube with a titanium alloy mesh on its outer side and carbon fiber filaments inside. A ceramic coating is adhered and fixed to the inner wall of the quartz tube, and connectors are installed at both ends. By wrapping the quartz tube with a 0.1-0.2mm thick titanium alloy mesh and fixing it to the quartz tube with an adhesive layer, a "glass-metal" composite layer is formed. This increases the overall impact resistance of the quartz tube to three times the original, reduces stress concentration at bending points by 40%, and lowers the transportation breakage rate to below 3%. The device also coats the inner wall of the quartz tube with a three-layer gradient ceramic coating: a zirconium oxide layer, an alumina layer, and a silicon dioxide layer from the inside out. This allows it to withstand high temperatures up to 1200℃, maintain an insulation resistance stable above 50MΩ, reduce insulation performance degradation by 70% during long-term operation at 600℃, and minimize the risk of leakage in humid environments.

Description

Technical Field

[0001] This utility model relates to the field of optical wave tube technology, and in particular to a multi-M type far-infrared carbon fiber optical wave tube. Background Technology

[0002] In fields such as industrial heating, home heating, and health therapy, the demand for efficient, precise, and environmentally friendly heating elements continues to grow. Far-infrared heating, due to its direct heat transfer and low energy loss, has become the preferred technology. Multi-M type far-infrared carbon fiber light wave tubes, based on the excellent electrothermal conversion and far-infrared radiation characteristics of carbon fiber, are structurally optimized to adapt to complex scenarios. They solve the problems of low efficiency, short lifespan, and uneven heat radiation found in traditional heating elements (such as metal heating tubes), meeting the demands of modern industry and civilian sectors for energy-saving, stable, and healthy heating. This represents a typical example of the iterative upgrading of heating technology.

[0003] One type of far-infrared carbon fiber light wave tube currently in use is a quartz tube as its main structure. This tube is highly brittle, and the multi-M shape is prone to cracking due to bending, transportation, and external forces during installation, which affects its lifespan and stability. Under long-term high temperatures, the quartz glass will gradually crystallize, and the insulation resistance will drop from the initial 100MΩ to below 10MΩ, which may cause leakage risk. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing technologies where quartz tubes are the main structure, which are brittle and prone to cracking due to bending, transportation, and external forces during installation, affecting lifespan and stability. Furthermore, quartz glass gradually crystallizes under long-term high temperatures, causing the insulation resistance to drop from the initial 100MΩ to below 10MΩ, potentially leading to leakage risks. Therefore, this invention proposes a multi-M-shaped far-infrared carbon fiber light wave tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-M type far-infrared carbon fiber light wave tube, comprising a quartz tube, a titanium alloy mesh on the outer side of the quartz tube, carbon fiber filaments inside the quartz tube, a ceramic coating attached and fixed to the inner wall of the quartz tube, and connecting parts installed at both ends of the quartz tube.

[0006] Preferably, the ceramic coating contains a zirconium oxide layer, an aluminum oxide layer is attached and fixed to the outer wall of the zirconium oxide layer, and a silicon dioxide layer is attached and fixed to the outer wall of the aluminum oxide layer.

[0007] Preferably, a plurality of conductive slip rings are rotatably connected inside the quartz tube, the output end of the conductive slip rings is fixed to the carbon fiber filaments, and an insulating ring is fixed on the outer wall of the conductive slip rings.

[0008] Preferably, the zirconium oxide layer is disposed on the innermost side of the quartz tube, and the silicon dioxide layer is adhered and fixed to the inner wall of the quartz tube.

[0009] Preferably, damping rings are fixed on both sides of the insulating ring on the outer wall of the quartz tube, and the two ends of the insulating ring are rotatably connected to the two damping rings respectively.

[0010] Preferably, an adhesive layer is attached and fixed to the outer wall of the quartz tube, and the titanium alloy mesh is fixed to the outer wall of the quartz tube by the adhesive layer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a 0.1-0.2mm thick titanium alloy mesh (5mm×5mm mesh size) is wrapped around the outside of the quartz tube and fixed to the quartz tube by an adhesive (high-temperature resistant silicone) to form a "glass-metal" composite layer. This increases the overall impact resistance of the quartz tube to three times the original, reduces stress concentration at bends by 40%, and reduces the transportation breakage rate to below 3%. The device also coats the inner wall of the quartz tube with a three-layer gradient ceramic coating, consisting of a zirconium oxide layer, an aluminum oxide layer, and a silicon dioxide layer from the inside out. This makes it resistant to high temperatures up to 1200℃, with an insulation resistance stable above 50MΩ. During long-term operation at 600℃, the insulation performance decay rate is reduced by 70%, and the risk of leakage in humid environments is close to zero, making it more practical.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1-4 As shown, this utility model provides a multi-M type far-infrared carbon fiber light wave tube, including a quartz tube 1, a titanium alloy mesh 2 on the outside of the quartz tube 1, carbon fiber filaments 4 inside the quartz tube 1, a ceramic coating 5 attached and fixed to the inner wall of the quartz tube 1, and connecting parts 3 installed at both ends of the quartz tube 1.

[0017] The overall effect of Embodiment 1 is that by wrapping a 0.1-0.2mm thick titanium alloy mesh 2 around the outside of the quartz tube 1 and fixing it to the quartz tube 1 with the adhesive used in the adhesive layer 9, a "glass-metal" composite layer is formed, which increases the overall impact resistance of the quartz tube 1 to 3 times the original, reduces stress concentration at bending points by 40%, and reduces the transportation breakage rate to below 3%. This device coats the inner wall of the quartz tube 1 with a three-layer gradient ceramic coating 5, which makes it resistant to high temperatures up to 1200℃, with insulation resistance stable above 50MΩ, and the insulation performance decay rate reduced by 70% during long-term operation at 600℃. The risk of leakage in humid environments is close to zero, making it more practical.

[0018] Example 2, as Figure 1-4 As shown, a zirconium oxide layer 6 is provided inside the ceramic coating 5. An aluminum oxide layer 7 is attached and fixed to the outer wall of the zirconium oxide layer 6. A silicon dioxide layer 8 is attached and fixed to the outer wall of the aluminum oxide layer 7. Multiple conductive slip rings 10 are rotatably connected inside the quartz tube 1. The output end of the conductive slip ring 10 is fixed to the carbon fiber filament 4. An insulating ring 11 is fixed to the outer wall of the conductive slip ring 10. The zirconium oxide layer 6 is located on the innermost side of the quartz tube 1. The silicon dioxide layer 8 is attached and fixed to the inner wall of the quartz tube 1. Damping rings 12 are fixed on both sides of the insulating ring 11 on the outer wall of the quartz tube 1. The two ends of the insulating ring 11 are rotatably connected to the two damping rings 12 respectively. An adhesive layer 9 is attached and fixed to the outer wall of the quartz tube 1. The titanium alloy mesh 2 is fixed to the outer wall of the quartz tube 1 through the adhesive layer 9.

[0019] The overall effect of Embodiment 2 is that the device coats the inner wall of the quartz tube 1 with a three-layer gradient ceramic coating 5, from the inside out: a zirconium oxide layer 6, an aluminum oxide layer 7, and a silicon dioxide layer 8. This makes it resistant to high temperatures up to 1200℃, with an insulation resistance stable above 50MΩ. During long-term operation at 600℃, the insulation performance degradation rate is reduced by 70%, and the risk of leakage in humid environments is close to zero, making it more practical. Through the setting of the conductive slip ring 10, it is connected to each interrupted quartz tube 1. Since the two ends of the conductive slip ring 10 are rotatably connected to the quartz tube 1, each quartz tube 1 can rotate. Due to the M-shaped setting of the quartz tube 1, the side closer to the M-shaped protrusion has a better heating effect during use, while the side farther away from the M-shaped protrusion has a worse heating effect. This rotation method can adjust the position of each M-shaped protrusion, making the heating effect more uniform. Through the setting of the damping ring 12, the damping of its rotation is increased, preventing it from rotating on its own, thus making it more stable.

[0020] Working Principle: In use, this device wraps a 0.1-0.2mm thick titanium alloy mesh 2 around the outside of the quartz tube 1, and fixes it to the quartz tube 1 with adhesive using the adhesive layer 9, forming a "glass-metal" composite layer. This increases the overall impact resistance of the quartz tube 1 to three times its original value, reduces stress concentration at bends by 40%, and lowers the transportation breakage rate to below 3%. The device also coats the inner wall of the quartz tube 1 with a three-layer gradient ceramic coating 5: from the inside out, a zirconium oxide layer 6, an alumina layer 7, and a silicon dioxide layer 8. This allows it to withstand high temperatures up to 1200℃, maintain an insulation resistance stable above 50MΩ, and reduce insulation performance degradation by 70% during long-term operation at 600℃. The risk of leakage in humid environments is close to zero, enhancing its practicality. This is achieved through the conductive slip ring 10... The system is configured to connect to each interrupted quartz tube 1. Because the two ends of the conductive slip ring 10 are rotatably connected to the quartz tube 1, each quartz tube 1 can rotate. Due to the M-shaped design of the quartz tube 1, the side closer to the M-shaped protrusion has a better heating effect during use, while the side farther from the M-shaped protrusion has a worse heating effect. This rotation method can adjust the position of each M-shaped protrusion, making its heating effect more uniform. The damping ring 12 is used to increase the damping of its rotation, prevent it from rotating on its own, and make it more stable.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
